Added subdomain, replaced public_html with empty folder!

Hello!

I’m creating a wordpress multisite and added a subdomain with the steps provided here: Pros and Cons of WordPress Multisite: Comprehensive Guide

This caused the public_html folder to be REPLACED by PUBLIC_HTML created by the subdomain (???)

I don’t have any recents backups of the website (stupid, I know) but I didn’t know that adding a subdomain would replace the public_html folder created in cyberpanel following official documentation.

Anyone have any trick up their sleeve restoring this?
